Description

Technical Field

[0001] The invention relates to the technical field of plastic tray separation, in particular to a tray separation machine. Background Art

[0002] In the field of packaging, a plastic tray is a carrying platform that can hold products, such as food trays and medicinal plastic trays. Medicinal plastic trays include injection trays, oral liquid trays or penicillin trays. The injection, oral liquid or penicillin medicine bottles are placed in the grooves of the plastic trays and then loaded into the medicine boxes to keep them stable in the medicine boxes so that two adjacent ones will not collide with each other and break. A tray separating machine is a device dedicated to separating plastic trays. The tray separating machine sucks the plastic trays apart through an adsorption head that can generate negative pressure. The tray separating machine is equipped with a rotating mechanism, which drives the adsorption head to rotate 90 degrees. Then the negative pressure of the adsorption head disappears and the plastic tray falls onto the conveyor belt. In this way, a stack of stacked plastic trays can be separated one by one and placed on the production line, thereby improving packaging efficiency. However, the existing tray pushing machines are prone to deformation of plastic trays during the tray separating process. Summary of the invention

[0042] The pushing mechanism 3 includes an upper supporting platform installed on the frame, a slide groove 9 is opened on the upper supporting platform 318 along the pushing direction, a pushing bracket 303 is movably installed in the slide groove 9, and a pushing plate 304 is installed on the upper part of the pushing bracket 303 extending out of the slide groove. The pushing plate 304 is an integrally formed flat plate to ensure the flatness and strength of the pushing process; a support track plate 8 is installed on the upper supporting platform 318 along the pushing direction at the positions on both sides of the tooth separation mechanism 4 to guide the box holder during the pushing process. A guide rail 307 is installed at the bottom of the upper supporting platform along the pushing direction, and baffles 305 are installed at both ends of the corresponding guide rails on the frame to prevent the guide rail 307 from detaching during the pushing process. A slide groove is extended from the lower part of the pushing bracket and a slider 306 is installed. The slider is slidably mounted on the guide rail. The guide rail is a dovetail-shaped protrusion, and a dovetail groove is provided on the slider. The guide rail and the slider are installed on the frame to ensure the linearity of the pushing process. A traction mechanism for towing the pushing bracket to move along the slide groove is installed on the frame. The traction mechanism includes a traction wheel 311 and a traction rope 301. The traction wheel 311 is installed at the bottom of the upper supporting platform corresponding to the pushing end position, the traction rope is wrapped around the traction wheel, one end of the traction rope is connected to the bottom of the pushing bracket, and a counterweight is suspended at the other end of the traction rope.

[0043] A pulley assembly is also installed on the mounting frame 312 between the counterweight block and the traction wheel on the frame, which can reduce the occupied space of the overall equipment and make full use of the equipment space. The pulley assembly 308 includes a fixed pulley group 315 and a movable pulley group 314. The fixed pulley group 315 is installed on the upper suspension 313 on the frame just below the corresponding traction wheel, and the movable pulley group is rotatably installed on the lower suspension 316 at the upper end of the counterweight block. The traction rope passes through the traction wheel, the fixed pulley group, and the movable pulley group 314 in turn to connect the counterweight block 309. The fixed pulley group and the movable pulley group both include at least two pulleys installed side by side. In this pushing mechanism 9, the pushing function of the box holder is realized by utilizing the counterweight block in combination with the pulley group. On the one hand, there is no need to configure additional electric components, which reduces the cost of the overall equipment. On the other hand, it also ensures the force stability of the pushing process. The tooth separation mechanism is installed at the end of the upper supporting platform. The tooth separation mechanism 4 includes a left plate 401 and a right plate 402 which are perpendicular to the upper surface of the conveying platform and arranged in parallel.

The protruding teeth 403 protrude from the two opposite surfaces of the left plate and the right plate; the box holder 2 is pushed to the tooth separation mechanism by the pushing mechanism to wait for suction and holder separation.

[0044] The suction support mechanism 5 is installed on the frame 1 at a position corresponding to the tooth separation mechanism. The suction support mechanism 5 includes a fixed frame installed on the frame. The fixed frame 501 includes a support seat 511. A vertical plate 512 is installed on the support seat 511.

A guide rod 509 is movably penetrated on the guide block 508 along the movement direction of the suction support cylinder. There are two guide rods symmetrically installed at the upper and lower sides of the suction support cylinder. The two guide rods can improve the stability of the suction support process and the service life of the suction support device. One end of the guide rod extends to the suction cup mounting seat 504, and a suction cup mounting seat for adsorbing the box support is installed on the suction cup mounting seat. The plate 503 has a plurality of suction cup support blocks 505 that cooperate with the box tray 2 installed on the side wall of the suction cup away from the suction cylinder. The thickness of the suction cup support block 505 matches the inner groove of the box tray. By supporting the inner groove of the plastic tray with the suction cup support block, it is possible to avoid a large amount of deformation of the plastic tray and affect the product quality due to the large adsorption force on the plastic tray. The suction cup support block is a conical block, and the suction cup support block is installed side by side on the side wall of the suction cup by bolts, so as to be adjusted according to the size of the box tray; a blowing air nozzle assembly is installed on the top of the suction cup, and the blowing air nozzle assembly includes an air nozzle fixing frame 506 installed on the suction cup, and a flat air nozzle 507 is installed on the air nozzle fixing frame, and the air outlet of the flat air nozzle is installed downward, and the size of the air nozzle decreases linearly along the air flow direction. The suction cup and the blowing air nozzle assembly are connected to an air pump. During the suction process, the suction force of the suction cup is provided by the air pump to realize the adsorption of the box tray. After the adsorption is completed, the box tray is separated from the suction cup by the air nozzle, thereby realizing the separation of the box tray. The box tray conveying device 6 is installed on the frame 1 at a position directly below the corresponding suction and support mechanism. The box tray conveying device is a type of belt conveyor or chain conveyor. An arc-shaped guide support plate 7 is installed between the corresponding upper support platform on the frame and the box tray conveying device. The lower end of the arc-shaped guide support plate is connected to the box tray conveying device. The box tray is adsorbed by the suction and support mechanism and then separated from the tooth separation mechanism, and then falls into the box tray conveying device along the arc-shaped guide support plate for transportation, thereby completing the overall tray separation function.

[0045] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments or to make equivalent substitutions for some of the technical features therein.
